Influence of Grid Structure on the Euler Solution

  • Using two types of patched grids, the influence of grid structure on the Euler solution of the flow around a wing with aileron deflection is discussed. One type is a partially discontinuous grid (PDG) and the other is a completely continuous grid (CCG). Van Leer's flux-vector splitting scheme and Jameson's central difference scheme are used respectively in PDG and CCG as the numerical methods to solve the Euler equations. Numerical results show that the two grids, CCG and PDG, have their own advantages and disadvantages respectively. Even though the useful results can be obtained in both grids,a suitable grid structure must be chosen depending on the flow and geometry to obtain better results efficiently.
